History of Helical Piers

Within the early 1800's, Alexander Mitchell developed power-installed helical fundamentals. These power-installed foundations were chosen for conjunction with the building of several lighthouses in the English tidal pot. More helical pile

Inside the 1920's, light-load-capacity manually installed helical screw anchors started to be utilized by the electric power industry for guy wires and as the anchorage for utility poles. Here screw pile

Within the fifties, the electrical power industry started to use power-driven helical screw anchors for tension loads to 36, 000 pounds of guy anchorage for towers and utility poles worldwide. Typically the primary use of these anchors was to resist tension or guy tons.

In the 1960's, the use of helical screw anchors was extended by the electrical energy industry for guy anchorage of transmitting towers with loads going above 100, 000 pounds. Technicians were starting to explore other applications of helical screw anchors, including foundations. This became apparent that helical screw anchors could avoid compression loads as well as tension loads.Click now screw pier installation

Inside the 1970's, helical screw anchors became the preferred method for guying electrical transmission towers and utility posts. Load capacity relationship started out to be recognized as a major good thing about helical piles.

In the 1990's, helical piles became an accepted technique of providing heavy foundations. Applications include, but are not restricted to, base retrofits, new construction, marine moorings, boardwalks, department of transportation projects, so that as tiebacks for all types of earth retention systems.install screw piers

At present, the use of helical piles includes non permanent and long lasting earth retaining systems (tieback anchors), underpinning systems for structures subject to settlement, pipeline supports, buoyancy control for underwater sewer lines, equipment mounts, street light foundations, and new construction projects with soil conditions that typically would not permit suitable capacities.

Within addition to providing strong foundation solutions to residential foundations, MacLean Dixie helical piles have been used to completely support a nine-story commercial building.
